"It" is one of Stephen King's most beloved novels. It is where many of his mega-fans often point to as a favorite. As such, the pressure was on for this adaptation to really shine.
Shine, though, it did. The nostalgic '80s feel to the movie was a pleasure for much of the audience, and the focus on childhood and coming-of-age elements managed to make the movie feel fresh even while it modified some of the details of the original story. Moving it forward thirty years was a perfect choice, and the casting of the Loser's Club was spot-on with the wit and personality of these characters being brought to life.
One of the parts of the movie I was worried about was Pennywise, but after watching the movie I can say that Bill Skarsgard's portrayal fit the role perfectly. They dropped much of the cosmic story--at least for this entry--and focused more on the chills and thrills.
All in all, Stephen King's "It" found new life in the movie adaptation and it is not a surprise that the second half of the story has already been approved for a release date in 2019.
